Question

 Consider the line segment LP with endpoint at L (-3, -5) and P (9, 7) and midpoint M.

What is the x—coordinate of N, the point that partitions segment MP in a 1 : 1 ratio?

A. 4
B. -4
C. -6
D. 6

Answer 1

• D. 6

Explanation:

M is midpoint of LP and N is midpoint of MP

Use midpoint formula:

• x = (x₁ + x₂)/2

Find x-coordinate of M:

• x = (-3 + 9)/2 = 3

Find x-coordinate of N:

• x = (3 + 9)/2 = 6

Correct choice is D
